Blue light stimulated opening of stomata, closing of stomata is also takes place by many other such mutants and mechanisms such as,

a.) npq1 mutants leads to closing of stomata

b.) In high PPFD leads to conversion of violaxanthin to zeaxanthin which will  leads to closing of stomata

c.) Green light in the 500 to 600 nm region of the spectrum, abolishes the opening of stomata

d.) Mutant of phototropin 1 & 2 (PHOT1/PHOT2)  leads to closing of stomata

e.) Starch content in the guard cell decreases during closing of stomata at the end of the day

Which of the following given statements will be correct for closing of stomata?
